Deprecation

This library is deprecated in favor of iOS 12 CAGradientLayer layer type .conic

See ConicSample project for CAGradientLayer examples ported from AngleGradientLayer.

AngleGradientLayer

AngleGradientLayer is a CALayer implementation of angle gradient.

Installing

pod 'AngleGradientLayer', '~> 1.0'

[Swift] Using in your code

import AngleGradientLayer
class MyView: UIView {
    override class func layerClass() -> AnyClass {
        return AngleGradientLayer.self
    }
    override init(frame: CGRect) {
        super.init(frame: frame)
        let l: AngleGradientLayer = self.layer as! AngleGradientLayer
        l.colors = [
            UIColor(red: 0, green: 0, blue: 0.5, alpha: 1).CGColor,
            UIColor(red: 1, green: 1, blue: 0.4, alpha: 1).CGColor]
    }
}

[Objective-C] Using in your code

(See demo project for more.)

#import "AngleGradientLayer.h"
@interface MyView : UIView
@end
@implementation MyView
+ (Class)layerClass
{
    return [AngleGradientLayer class];
}
- (id)initWithFrame:(CGRect)frame
{
    if (!(self = [super initWithFrame:frame]))
        return nil;
    AngleGradientLayer *l = (AngleGradientLayer *)self.layer;
    l.colors = [NSArray arrayWithObjects:
        (id)[UIColor colorWithRed:0 green:0 blue:0.5 alpha:1].CGColor,
        (id)[UIColor colorWithRed:1 green:1 blue:0.4 alpha:1].CGColor,
        nil];
    return self;
}
@end

Notes

When working with semi-transparent views, be sure to set backgroundColor property on the layer’s view

myview.backgroundColor = UIColor.clearColor()

backgroundColor by default is nil, blending to black color.
